Our eight year old tabby seemed to have contracted really sensitive skin as of late. He is fine until you pet/tap/scratch his back near his tail then he starts biting or chewing anything nearby. Blankets, couch, cardboard, his own front paws. Should we take him to the vet or is this something that will resolve on its own?
